By far the cheaper Lifepo4 ever. Less than .10 per wh.
Rated at 1920wh and I've tested 2 of them and got 1950wh.
Was going to post this but it seems I always get deleted everytime I post a deal.
Working back from you numbers, it appears you might have been multiplying 12vx150ahx4 batteries to get that number and were referring to capacity?
In that case, multiply the 150ah x nominal 12.8v x 4 batteries for 7680w/h. Then multiply by inverter efficiency (check inverter, but 80% is conservative in most cases) to get usable capacity, which in this example would be 6144w/h

Already screwed it shut, but I did NOT look for lengthwise compression straps, but it dawns on me that in a confined metal box, with end 'cages' on each end, the cells are pretty much already limited on just how much they can expand, so feeling secure the cells are secure.
App screenie shows cells appear balanced.

Would be really interested in seeing if the QR codes can report the cell info. Actual Eve 150ah would be awesome.
Also, have you by chance tried to connect using the Overkill Solar BMS app? If it can connect, it should show a lot more detail on BMS config and higher resolution on battery state.

Thanks Martog...you rock!
Overkill app says build date of Sept 26, 2024.
With great power, comes great responsibility!
I probably should have warned you about messing with the BMS settings using that Overkill app as it has the ability to overwrite the factory defaults and you could potentially create very unsafe operating parameters. So probably not change any factory settings unless you absolutely know what you're doing. I'm sure that is one reason the factory supplied apps are all nerfed to some degree.
But now that you can see all the BMS parameters, you can understand how it is calculating SOC, LVC, HVC, capacity etc. You may or may not agree with the factory defaults. They tend to be more aggressive than is advised by the experts over at diysolarforum.com. But if it's the factory defaults it's hard to argue since EW will be the ones (presumably) providing the warranty.
Congrats. This looks to be a great deal and the battery appears to offer all the features as advertised. And the use of the ubiquitous JBD BMS not only means it works with the Overkill app but also that replacements will be readily available in the future if needed.
Solid deal all around.
